SAMSUNG Repair Guide: Common Issues and Fixes
| Brand | Model | Fault | Detailed Problem | Solution | By |
|---|---|---|---|---|---|
| SAMSUNG | UN48H4203AG US04 | Does not turn on, LED blinks. | Defect in ic310 | Replacement | <small>electronicssupplyparts</small> |
| SAMSUNG | PL50C450B1 | Blurred image | VR5301 1K adjustable resistor changed. | Check VR5301, re-solder Q5303 and Q5304. | BRITO |
| SAMSUNG | LN32A330J1 | Turns on has sound but without turning on the backlight | Inverter board with f1 open, f2 and f3 ok inverter board without power supply | I replaced f1 using a fuse taken from other inverter boards sound in the store | Robusto |
| SAMSUNG | CL29K40MQ | Image shifted right side horizontally with shadows | Resistor r204, 3k9,d409,1n4148,r424, 680k | DJ PITUKA | |
| SAMSUNG | CL29K40MQ | Image pulled to the side with horizontal shadows | R205 ,3k9, near the vertical heatsink | DJ PITUKA | |
| SAMSUNG | LN26C350D1 SQ01 | Red LED stuck, won't turn on. | Check 13v on bd7002, if it is zero, or close to zero, check possible short on cp26 - vcon board | Replace/withdrawal | electronicssupplyparts |
| SAMSUNG | LN26C450E1M | Does not turn on, red LED is on | Change 3v3 az1031 regulator | giovano eletronica | |
| SAMSUNG | T22A300 WDS2 | With audio and dark screen (without back light) | Ic oz9998bgn controlador dc / dc | Changing the circuit in the power supply | Marcos Vinicius - Salvador. |
| SAMSUNG | T24B350LB | If it turns off, the stand by LED flashes | Lack of voltage to light the LEDs | Place a 2k resistor between pins 13 and 14 of the power supply connector. | Eletronicaaeb |
| SAMSUNG | LN32R71BX | Restarting directly, back light normal, power supply normal, defect on the main board | Open ra224 | Check all the resistors around the memory ic223, ra221 to ra228, all of them | Alex Lopes <small>This email address is being protected from spambots.

| SAMSUNG | LN32D550 | Image flashing and then with the side of the screen with lamps half off (dark image) | Main board | thedrads | |
| SAMSUNG | UN40F5500 | Stby blinks, but tv doesn't turn on | Power supply keeps varying pfc and voltages in the secondary | 10r non-primary resistor rs802 | ajm |
| SAMSUNG | UN32EH4500 | Tsound is no +b in the secondary | Dm858 shorted... | Review also dm859 | Alextecnico |
| SAMSUNG | PN43F4000 | Does not turn on, just standby | Open resistor in the second photocoupler | Resistor 4k7 | Marcelo |
| SAMSUNG | PL42B450B | No image | Voltage on pin 1(in) of the u5409 (7805) below 5v (measure the voltages using pin 2 of the u5409 as a reference), capacitors c5518 and c5519 on the leaky buffer board. | Swap c5518 and c5519 near the u5409 (7805) on the bμFfer board. I hope I helped! | Julian C Braga |
| SAMSUNG | CL21C650ML | Reduced frame | Cr407s na deflectora | Replacement | osvaldoitq |
| SAMSUNG | UN40H5103AG | With sound, LEDs on without image, giving the impression of a defect on the display | I checked on Vcon the voltages vghp 30v, vgh, vgl were absent, to my surprise, I replaced the main board and it solved the problem. | It seemed to me that if the vcon supply voltage is either below or above 12v the ci tcon goes into protection. | Eletrônica Valdecir |
| SAMSUNG | T27A550 | Turning off by itself or not turning on | Check pin 4 of the icm801cs if it has less than 12v check for leakage due to glue, in the resistors rm861 rm862 cm854 rm864rm867 rm866 | Lacerdasuntzu | |
| SAMSUNG | UA40J5200AK | Dead not work power supply (bn44-00851a) | Not found | Please send schematic at my email id (This email address is being protected from spambots. You need JavaScript enabled to view it.) | Abdul Ghani |
| SAMSUNG | CL29Z58MQ | Dark screen, normal sound and lit filament. | With the oscilloscope I found that the vertical was ok, tsoundfore, it was a problem with the video signal. | It was the resistor rv201 (10k) which was 15.5k. It is next to, to the left, the microprocessor. | Chumbão |
